The invention comprises in generals. machine for wrapping regenerated cellulose, paper, or similar wrapping about a carton or package, there attests I being a tape wrapped within the wrapper and having an end extending from the edge of the wrapper a predetermined distance to provide an opening tab. Both the wrapper and the tape are formed from a continuous web and fed at predetermined rates of speed so that the length of the tape fed will be longer than the wrapper so as to provide an extending tab. Cutting members operate in timed relationship with the feeding mechanism to simultaneously cut the tape and wrapper. During the feeding operation of the wrapper a predetermined amount of adhesive substance is applied thereto in a predetermined position whereby the tape may become fastened to the wrapper. Articles arranged in a carton or package are fed in a predetermined position with respect to the cut wrapper and cooperating tape so that during continued movement of the package, a wrapper will be formed about the package or carton. During the movement of the package throughout its course of movement through the machine, certain folding mechanism folds the wrapper about the carton or package,

while other adhesive material applied to the wrapper seals the longitudinal edges of the wrapper as well as the ends thereof. Detector mechanism operating in timed relationship is provided to prevent the feeding of webs and the cutting of wrappers therefrom when a package is not in a proper predetermined position relative to the finder or locating elements of the detector mechanism. 'Deliv'ery mechanism is provided at the timed relationship with other mechanism of the machine so as to receive and deliver the wrapped, sealed packages to a predetermined support.

The particular wrapping machine herein illustrated for the purpose of explaining the invention comprises a suitable frame or supporting structure I. A transverse shaft 2, driven in any suitable manner, such as by an electric motor, not shown, is mounted in suitable bearings 3 and 4, Figs. 1-3. The main drive shaft 2 drives a sprockct ii, Fig. 2, and a sprocket chain 6, driven by the sprocket El, drives a sprocket l which is mounted on a shaft 3 made in two parts 9 and i0 co-extensive with each other as more clearly shown in Fig. 39. A wrapper ieed roll H mounted on a rotary shaft 82 is driven from the end it? of the shaft 8 by means of gears 63 and id, Figs. 1 and 6. A tape feed roll iii mounted on a shaft i6 is driven from the end ill of the shaft 8 by gears 17 and i8, Figs. 1 and 6.

Wrapper and tape feed and cutting mechanism A continuous web of wrapping material I9 is fed from a roll Eli mounted on a shaft 2!. The shaft 2i is operatively supported by a bracket 22 rigidly fastened to the top of the frame I. The wrapper i9 passesabout a booster roll '23 and over an idler roller 24 and then between the rollers H and 25,,the roller '25 being driven by the shaft i2 by means of the gears 26 and 21, Figs. 4 and 5. The feed rollers I i and 25 feed the wrapper 49 over a guide 28, Fig. 1, to a position betweenv arcades oi the-shaft 8 through the. intermediary oi the gears it and it, Fig. 'lheieed roller ill is driven by the shaft it through. the intermediary of the gears it and til, t and ii. The tape upon operation of the arm ti.

i plate or platform t t. The pusher ht is fixed to a 'arm ill.

.feed rollers are designed to feed tape to the cutters it and it at a rate faster than the feeding rate of the wrapper so that a predetermined amount of tape will extend beyond the lower leading edge of the wrapper.

The wrapper is, Fig. 1, passes between a bar it, intermittently operated by a cam actuated arm ii and an adhesive roller til, the wrapper coining in contact with the adhesive roller ii. intermittently The roller it which is relatively narrow, Fig. 4-, obtains the ad hesive from an adhesive receptacle t8 and de posits a spot oi adhesive upon the wrapper in pre-- determined position at each reciprocation oi. the After the predetermined amounts of wrapper and tape have been fed, they are cut by the cutters iii and to. The severed wrapper and tape then pass between the guides i t and and between the rollers it and ill. The roller it; is a rigid revolublv driven roller and drives the cornpanion roller t'i. As the tape is fed faster than the wrapperand inasmuch-as the tape and wrapper are severed simultaneously, the tape will eirtend beyond the lower or leading edge oi the wrapper and is received between the rollers it a and ill before the wrapper isso received. its the tape and wrapper pass between the rollers it and ill and inasmuch as the tape is juxta positioned with respect to the adhesive from the wrapper, the

tape will be fastened to the. wrapper, there always being a projecting edge in the iorm. of a tab extending from the lower leading edge of the wrapper. The rollers it and ill feed thewrapper with the tab adhered thereto into-proper posi tion to' become engaged by the oil-coining article or package to be wrapped, the wrappcrbeing arranged and supported in the guide member to a The articles or packager to he wrapped are placed on a continuously moving conveyor iii which is in the iormof an endless belt operating between guides/Figs. 1 and "i, from a point forwardly of the wrapper support ilt,to. the left, Fig. 1. An abutment iii, Fig. '7, inthe. form of a bar extending across the open end or the conveyor stops the first package till", Fig. '7, on its movement to the right where an intermittentlyoperated pusher ti pushes the package til from its sta tiona'ry position onthe conveyor iii to a receiving driver it, Fig. 7, which is slid'ablv mounted on upper and lower guides and ti respectively as more clearly shown in Figflt. Thedriver tit-is driven by a limit or which is operatively connected to a cam lever tit in the former a hell-crank including the arms tit and iii, Fig. 2, the cam lever 'being drlvenby a cam ill! on the rotating shaft til.

The shaft til has a beveled gear ti t lined thereto, Fig. 2, which meshes with a beveled gear tltt fired to the power shaft t, Fig. 2. The pusher tilt is driven from the main drive shaft ii and intermittently reciprocates to push a pacltage from the conveyor 5i onto the. table iitin a position directly opposite the wrapper in position it and properly centered with respect to the wrapper, there he lngapacltage stop tit, Fig. '2, to prevent unauto the shaft tit.

d secondv pusher $1 is slidably thorired movement or shifting of the package on the table 5t.

mounted hetween guides it formed on the table tit and moves the paciragein a predetermined po- 'eition into a proper-pocket W or an arm lid iii-an intermittently rotating transfer wheel ii, Fig. l.

Pacheco transfer mechanism The transfer wheel ii, Fig. i, is fixed to 2. r0 tatahly mounted shaft it and comprises a plurality of spaced arms it. Each arm is provided with a cut-away portion or notch over which lies a plate "it held in position by pins it and urged fined thereto, which gear meshes with a gear BI fixed to a shaft it. The shaft M is driven by means of a chain lit passing over a sprocket B4 on the shaft it, Fig. 2, and a'cooperating sprocket; iiii, Fig; 3, fixed to the shaft 2.

The pusher til has 9. lug 8t, Fig. 12, fastened thereto, to which there is pivotally connected a limit ti, Fig. 1, pivoted at site one arm 89 or a drive lever 9t. ihe driving lever iii) is pivotally mounted on a stud iii, and hasits lower ar'm iii pivoted-to a link tit as indicated at St. This link to is pivotally connected to a crank fixed operated reciprocally from the shaft til.

The feedrolls to and it move the severed wrapper with its attached tape to theposition it as previously irientioned- The feed roll All car ries a gear til, Fig. '5, which meshes with a gear ti on the shaft iitupon which the ieed'roller it is mounted. I Thus, the feed roll it is positively driven by the positively seven feed roller til through the gearing just described, Fig. 5. The shaft til has another gear iltiormed thereon, Fig. 6. which meshes with a near tilt on? the shaft WI. The elicit itifli llrs. 2, ii and '7, has a sprocket wheel it'll iliced thcret l ige zand '7, and is driven by a sprocket chain tilt, Figs. -2 and 7, which is driven by a sproclret, not shown, mounted on the previously described driven shaft is.

The conveyor iii includes an endless belt which is driven by a pulley tilt, Fig. l, fixed to a'shaft Gilli. The shaft tilt, Fig. 6, has a gear ittt fixed thereto which gear meshes with an idler gear ill! mounted on an idler shaiti'tt. The idler gear The wrapper lit, Figs. 10 and 11, includes the Therefore, the pusher M is out portion ii i from the wrapper web it and the tape portion lit from the tape web'rv which is secured to the portloni it by the spot of adhesive as shown. The tape i it extends a predetermined distance beyond the edge oif the wrapper portion iii to provide an easy opening tab i it, Fig. 10. The transfer wheel operates in proper timed relationship with the pusher ti and, therefore. as the pusher ti moves to the right, Fig. 12, and engages the package ht, the pocket 69 will be in alinement with the movement or the package. During the movement of the pacliageintothe pcciret til, the wrapper will pass between the angle H4 and the edge lit? oi the plate Ielg. 12, thereby partially forming the wrapper alooutthe package. Continued movement of the package into the pocket will position the'package with respect to the wrapper so that the wrapper will engage the top and bottom and one side or the package with the free edges of the wrapper extending a predetermined distance beyond the uncovered edge of the package. As soon as the package with the wrapper partially formed thereabout is totally received in the-pocket fat, the transfer wheel will rotate a partial revolution (in this case degrees) to bring another pocket in position to receive the next package. Upon movement of the transferwheel, the package will be at the bottom of the wheel "it in the position as clearly shown in Fig. 16 and in juxtaposition to the folder i it and adhesive applicator Ill, Figs. 15 and 16.

Folder and adhesive applicator a'nechanism When the package is in the position shown in Fig. 16, the folder lili will move upwardly in an arcuate direction to the right, Fig. 1', and fold the left flap, Fig. 16, from the dotted line position in that figure to the full line position as shown in Figs. 15 and 16 and against the side of the package. The folder H6 is fixed to the upper arm H8, Fig. 1, of a lever lit which is pivoted on a pivot shaft 5%. The lower arm iii of the driving lever i it carries a cam follower iii? which is operated by a cam its, Fig. 3. The cam its holds the free edge of the folder in position against the package as clearly shown in full lines in Figs. 15 and 16. During this folding operation and after the free edge is folded against the package, the adhesive applicator will apply adhe 'sive along the inner side of the sole remaining free edge. The applicator ill is in the form of a comb having teeth which have adhesive applied thereto from the adhesive in the container i2 5, Fig. l. The applicator iil is, fixed to one arm of a U-shaped lever liii which is pivoted at 826. The other arm of the Ushaped lever iiiil is pivotally connected to a link i271 which is pivotally connected to a crank its on the shaft it. its the applicator moves up to apply adhesive to the inside free edge of the wrapper. the wrapper will be held by an abutment ltd, Fig. 16. The abutment I29 is in the form of a shoe which forms a guide I38 to cause the glued free flap to be pressed against the aforesaid folded flap and become fastened thereto during rotative movement of the transfer wheel another 90 degrees. When the transfer wheel has moved this last 99 degrees, making a total of degrees from the time the package was first received by the transfer wheel, the package will be ejected from the wheel into a proper receiving channel or support by suitable ejector mechanism.

Ejector mechanism The ejector mechanism, Fig. 1, comprises a pair of spaced arms l3i which extend on opposite sides of the plate it. These arms are fixed to a slide block i322, Fig. 1, operating in upper and lower guides i331 and i3 3 respectively. I-he slide block is operated by a driven arm 35 and a connecting link we. The arm B35 is fixed to a rock shaft i3l, Fig. 1. The shaft it'll, Fig. 2, has a lever i318 fixed thereto which is pivotally connected at N39 to a link i ifi. Thelink ass is pivotally connected at i ii to the gear do which is mounted on the aforesaid driven shaft it. Thus, during rotative movement f the shaft it and gear fill, the arms it' l will be given reciprocatory movement and, as the package is conveyed by the transfer wheel ii to ejecting position, the arms i235, when they move to the right, Fig. i, will engage the package near its ends as shown in Fig. 18 and eject the package out of the pocket 69 and position the package in a guideway M2. The guideway Hi2 comprises spaced lower rails Hi3 and a central lower supporting rail M l which support the package at its ends and intermediate the ends as clearly shown in Fig. 22. The guide M2 also comprises an upper package engaging rail or bar Hi5 which is urged downwardly by the springs MG arranged between the member i 35 and the upper member Mi.

The arms iii carry folding fingers M8 at their 1 lower ends, Figs. 18 and 19. These fingers Hi8 are-adjacent the ends of the package and are adapted to fold the wrapper inwardly along one side of the package at the ends thereof as clearly shown in Figs. 18 and 19. These fingers .18 are provided with slots or recesses its which are adapted to receive the stationary tucking folders or fingers l5!) against which the wrapper on the other side of the package is being pushed during the ejecting movement of the package from the transfer wheel ii. Thus, as the package is moved from the transfer wheel 'ii and onto the guide M2, the wrapper overhanging the ends 0 of the package on both sides thereof will be tucked or folded inwardly as clearly shown in Figs. l8, l9 and 20, particularly Fig. 20. When the arms i3! reach the extreme end of their ejecting movement, the edge folded by the fingers Hi8 will be positioned so that those folds will lie inwardly of the stationary folders I50. Thus, the folds on both sides of the package and at each end will be folded snugly against the package and maintained in that position by the stationary folders NW. at the end of the ejecting movement oi the package and after the package has been moved a predetermined distance in the guldeway SL555 by the arms idi, transport or conveying mechanism ilii engage the package which is then positioned between the stationary rigid folders or fingers ifrii and continues the movement of the package along the guideway i 32 where other tucking and folding mechanism operates.

Transport mechanism The'tr ansport mechanism comprises a pair of arms as: carrying spaced fingers i552, Figs. 1 and 22, which intermittently engage successive packages and move them forwardly along the guideway it. This transport mechanism may be of any conventional type or design just so it performs the function intended. In the present instance this transport mechanism is moved to the right, Fig. l, to engage and move the packages and then recedes with a backward, downward movement, being operated in the present case through a system of cams I53 mounted on the shaft 2. Therefore, the transport mechanism will operate synchronously and in timed rela tionship with the other operating elements and mechanism. As the package Ell is being moved along the guideway M2 by the transport mechanism iiii, the free edges of the package at the bottom thereof will become engaged with inclined rigid stationary folders iii i.

Folding mechanism The folders i5 3 incline upwardly and become thicker as the package progresses along its path,

All

while the fingers loll decrease in sine. Therefore,

this progressive movementoi the package along the guldeway will fold the iiaps along the bot tom of the package at the ends thereof upwardly to the positions first shown in rig. Wand finally to the position shown in Fig. 25. The folders lfi l hold the folded flap tig tly against the ends of the carton or package as clearly shown in Fig. throughout the inoveinen't oi the package along the guideway and until the upper flap is to be folded. While the package is still on the guideway and held by the folders ifitythe free top flaps atthe ends of the package are given an application of suitable adhesive by an adhesive applicator.

Adhesive applicator 'I his adhesive applicator, Figs. 23 and 24, com prises a bracket its which is fastened to part of the frame'l and includes a base iiili which is located a predetermined distance below the bottom of the guideway Hill. A shaft iii'i journaled insuitable bearings in the bracket and frame is driven by a gear iiiil, Fig. 23, which meshes with an idler gear its, Fig. 2, the idler gear being driven by gear ti. on shaft lit, Fig. 2. The shaft i5? carries gears lliil which mesh with gears iiii on shafts it? supported by the reservoirs Applicators led in the form of disks are fixed to the ends of the shaftsi and extend down a predetermined distance into the reservoirs [Hi3 so as to obtain adhesive in these reservoirs and apply it to the projecting end flaps on the top oi the package at the ends thereof. These disks lo l are positioned so as to apply adhesive to the inside of the remaining flaps, the said disks being positioned outwardly of the rigid folders lii i as of the frame i.

clearly shown in Fig. 24. The disk is constructed and arranged that its periphery will be substantially coincidental with the inside of the flap to be glued so that the inside edges oi the end flapswill come in contact with-and be engagecl by the periphery of the rotating dist: which has the adhesive applied thereto. Flap guides ltd may be fastened to a part oi the guideway and extend downwardly as clearly si'iown in Fig. 24 so as to positively insure the iiap coming into contacting engagement with the adhesive carrylng disk to insure adhesive being applied thereto. The members lllil may be provided with inclined tall-pieces l-liii so as to insure the positioning oi the ing operation, the transport mechanism moves the package still further along the 'guietlewa'y to the extreme outer right-hand end thereof, the package being constantly held by the fingers iii i. At the end of the g'uideway the package with the extending glued tabs is elected or moved to position to be acted upon and to be engaged by the delivery mechanism which lolds the remaining flaps against the ends of the package where they become glued.

Delivery mechanism Delivery mechanism is located at the extreme right-hand end of the guldeway Mill, and coneprises two spaced disks it'i, Figs. 28, 29 and 30, fixed to a rotary shaft iiiii, there being a spacer It!) arranged between the disks and lined thereto. The shaft lull is supported in suitable hearings in an attaching bracket Hill, which is fixed to a part A gear ill is fixed to the shaft I68 and drivesthe same, obtaining its driving power from an idler gear l'iii, which meshes with. a gear lit fixed to the afcresaiddriven ltiii flaps with respect to the disks. the g1u-,

if The distance between the spaced disks Hill is considerably less than the lengthoi the package. The package, therefore, extends a predetermined distance beyond the outer races oi. the disk. A stationary cam il ils arranged at one side of a disk lei, and operates a plurality of carrying arms or fingers lit, which are pivotally connected to the disks by means of transverse rods i'it.

"lfl'iese' fingers carry lugs l'il preferably formed integrally therewith, and are held against the cam by springs lit, Fig, 28. The springs i'lB hold the lugs il'i against the periphery of th'ecam lit. Thus, during rotative movement of the disks, the arms are moved throughout a plurality of angular positions. In delivery position the arm will be in the position shown in Fig. 28, whereby a package til will rest upon the arms i'lb" with the righthand side of the package engaging the peripheral surface of the dislrs. Uuringrotative movement or the disks the lugs ill will be engaged with the smooth circular surface of the cam until their associated arms iiii, upon which the packages rest, attain the upright position shown in Fig. 28, in which position the packages will be arranged in adjacent relationship on a receiving guide or platform its. During continued rotation of the disks, the lug or shoe illl will follow the cam surface of'the'cam ii 'l causing the fingers lili to be moved to the various positions shownin Fig. 28. These positions are attained because the springs. lie hold the lugs or shoes ill in constant engagement with the periphery of the disk. Therefore their angular position is adapted to be changed as set forth. an arcuate spaced plate ll'iil extends a predetermined distance on each side of the pair or" disks Hill, the space between said plates being substantially equal to the length of the package. Therefore, when the package is moved from the position designated bythe letter ii. in Fig. 28 to the position E with the disks rotating in the direction oi the arrow in Fig. 28, the extending flap on the upper side of the package at each end thereof will be pressed down against the ends of the In other words, the extending flaps on the package are pressed between surfaces spaced a distance apart substantially edual to the length or the package. Therefore, when the package is pushed within this space, the flaps are caused to fold downwardly against the ends of the paciraaeand as the in sides of these flaps have an adhesive applied thereto, the flaps will be permanently stuck to the bottom and side flaps causing the package to be completely wrapped and sealed. The spaced plates ltd extend substantially one quarter of the way around the disk, from receiving position to discharging position. Therefore, the ends of the flaps are caused to hug the side walls and become pressed tightly against the ends of the package. .a spring-pressed top plate lti may be arranged above the receiving table i "it, as shown in Fig. 28, to maintain the packages in properposition.

Tape guide in view of the fact that the tape 3t is fed faster than the wrapper ill, means are provided to guide, support and position the tape to maintain it in a certain position with respect to the wrapper. Due to the fact that the tape which is secured to the wrapper at only one point is relatively narrow and has a tendency to shift and curl, the present tape guide mechanism is provided. This guide mechanism comprises a guide shoe idii, Figs. 1 and 5, which is relatively long vertically and adapted to reciprocate vertically and engage the tape. When the tape 8 5 is fed,

the shoe moves with the tape in the same direction in which the tape is fed and maintains the tape in a proper position with respect to the wrapper i9. This tape guide is timed so as'to follow the timed movement of the knives so that when the leading or lower edge of the tape is in a position to enter the guides i l and t5, this tape guide will hold the tape adjacent the wrapper and prevent it from curling or shifting its position. When the cutters tend to approach each other, the shoe N32 is moving away and upwardly so as to not foul the knives. The parts are so timed and constructed that the shoe ltiz will be at the extreme upward position of its travel during the actual. cutting operation and immediately after the cutting operation will drop down and guide the tape as previously mentioned. Therefore the shoe moves upwardly and downwardly to guide the tape in proper timed relationship with respect to the actual cutting of the knives 2d and 30. Also, this guide serves to stick the tape to the wrapper because, as previously described, the wrapper, prior to being cut, is provided with a smooth dab of glue in a position so as to be in alinement with the tape. Therefore, this shoe pushes the tape against the wrapper and assists in maintaining the stuck connection. The upper edge of the shoe is? extends between the feed rollers l5 and 3?, Fig. 5, said rollers being grooved or relieved to receive the upper end of the shoe. The shoe is provided with a tail-piece iBS fastened to a guide block i84 The guide block i8 3 carries pins i855 which extend through suitable apertures provided in a guide yoke BS6 which is rigidly fastened to a block l8! connected to the bracket 22. A bellcrank I88 has onearrn thereof it? connected to the slide block ltd by a pin and slot connection designated generally by the numeral tilt, Fig. 4, and its other arm lill pivotally connected to a link I92, Fig. l. The bell-crank is pivotally mounted on a stud or shaft its, Fig. 1. The link I9! is also connected to a bell-crank lll l which bell-crank Hi l is pivoted at Fig. l. and has a cam follower tail which engages a'cam lB'i mounted on the previously mentioned shaft This cam follower tilt; is maintained in constant engagement with the cam ifil'l in any well known manner, such as by a spring (not shown).

Another mechanism for assisting in maintaining the tape in proper position with respect to the wrapper comprises a tape locator or positioner l98-as shown in Figs. 8 and 9. This tape posi tioner I98 is located immediately below the table 54 and has its tape locating ends arranged in proper position with respect to the guide 53 to maintain the tape in a predetermined position with respect to the wrapper when the wrapper is arranged in the position designated formerly by the numeral E9. The positioner lilii comprises a pair of cross levers W9, Figs. 8 and 9, pivoted at 200, and includes pusher arms l. The pusher arms are maintained in open position as shown in Fig. 9 until the tape is arranged therebetween at which time the jaws will close as shown in Fig. '8 to properly position the tape. The ends 28! of the positioner 698 are normally urged in closed position by means of a pin and spring 202 and 203 respectively and are forced open by means of a cam 204, the cam surface 205 of which is adapted to cooperate with pins 2%. Therefore, when the cam is in the position shown in Fig. 8, the cam surface 205 will have no effect on the pins and the spring iitli will close the ends 263i position with respect to the package, a tucker or kinking finger 288, Figs. 13 and 14, is arranged at each end of the package so that when the package strikes the wrapper as the package is being moved into the pocket 69 of the transfer wheel ii, the ends of the wrapper will receive a pre-kink or fold, thereby assisting in maintaining the wrapper in proper position with respect to the package and preventing the wrapper from shifting with respect to the package during movement of the package into the pocket 69.

Detector mechanism It is desirable that the webs is and 34' be not fed when a package to be subsequently wrapped at a predetermined time is not present in order that no wrapper or tape may be cut when no package to be wrapped is at a predetermined position on the feed conveyor. Detector mechanism is, therefore, provided to prevent the cutting of a wrapper if no package is fed. In other words, if no package is present at a predetermined point on the conveyor, the mechanism for feeding the wrapper web and the tape web and the mechanism for the cutters will be maintained inactive until such time as a package is present at the said predetermined position. However, this detector mechanism in no way affects the opera tion oi the machine as regards the already cut wrappers and the packages which have already passed beyond the detector mechanism. In this respect only the web feed mechanism and the cutters are prevented from operating while the rest oi the machine continues to perform its nor mal cycle of operation. This detector mechanism comprises a detector element 269, Figs. '7 and 32 to 3ll, which is rigidly attached to an arm or lever iiiii pivoted at 2M and having a rigid offset rear portion 232 (Figs. 7 and 32 to 88). A cam 253 is formed on the upper edge oi. the member 2H] on the arm Hi2 thereof rearwardly of the pivot 2H and is adapted to be engaged by a pawl or cam operator 2 l lcarried by the first mentioned pusher 53. Therefore, when the pusher 53 moves forwardly to displace a package from the belt of the conveyor mechanism til, the pawl or cam operating mechanism 2H3 will operate on the cam 2 it and depress the arm 2 i2, causing the forward end 205% to raise. However, continued forward movement of the pusher 53 will move the pawl 2H5 off of the cam surface 2H3 and allow the lever 2H. to move upwardly causing the member 209 to move downwardly, there being a spring 2 i 5 fastened to the end of the lever 2l2 to pull this end in an upward direction. In other words, there is always a tendency of the detector element 2M to be urged downwardly and maintained in that position except when the pawl 2M is in engagement with the cam 2E3. Therefore. if there is a package on the belt beneath the detector element 269, the packages are free to slide thereunder, but if there is no package in the proper predetermined position, the detector element 209 will move downwerdly and prevent improper ieeding of packages into the machine. Therefore, the packages are fed in proper timed relatiom ship with the operation of the detector element 209. In order to prevent the detector element 209 from raising. on the return movement oi the pusher till, the pawl ti t, which is pivoted to the pusher 53 at tilt, will engage a finger till (Figs. 7 and 37) and be rotated thereby so that it will not engage the cam Eli; upon the rearward or return stroke of the pusher lit. Therefore, upon 'forward movement of the pusher lit, the cam will be depressed, causing the detector end till to be raised ashort period of time until the member 2% slides off the cam tit at which time the detector 2% will be in its down position. Upon return movement of the pusher the pawl will be prevented from coming in contact with the cam tilt. in other words, the cam is only engaged once and that is on the forward movement oi the pusher. The detector element tilt is normally urged downward by means of the spring iiili. At the end of the return movement ofthe pusher 53, the element ii it will strike a stationary meinher or finger til (Figs. 7 and 37) and be rotated thereby to its original position as clearly shown in Fig. '7, When the detector toil is held in its intermediate position, by its engagement with the top of a package, the package is free to continue movement along the conveyor and into the machine and the webs will continue to be fed and out. it, however, there is no package under the detector element Eliiil, the detector element will drop until it en gages the belt of the conveyor means iii and will remain in that positio'n and prevent oil-coming packages from passing through the machine and becoming improperly positioned until the nest forward movement of thepusher iii; causes the cam to become engaged by the pawl ti l, thus raising the detector. If there are other packages on the machine, they will engege the detector element tilt and be temporarily held from being fed. Thus, during the next cycle of operation, when the detector element is again raised by means of the pawl Elli engaging thecarn till, these packages will be permitted to feed through the machine in regular proper order and in tinied relation with the pusher till.

When there is a ncclrage on the belt under the detector, the feeding and cutting means will operate so as to provide a. wrapper for that package, but if no package isuncler the detector when it descends, it will operate mechanism to prevent feeding of the wrapper and also to prevent the cutting knives from operating. The end of the lever tit carries a rod till, Fig. 32, having 9. lug flit formed on its lower end. The position of this lugv determines whether or not the wrapper feed mechanism and cutters ore to operate- The arm tit of a belt-crank 212i, pivoted at tilt, Fig. 35, is operated by the arm 225i, Figs 2 and 3, of the'saio'l hell cranlr engaging a cam'ittl fixed to the driven shaft tit. During rocking movement of the arm 22d of the belhcranl: 222i, the arm tilt will engage the lug and force it against 9. lug iliiii which is rigidly fined on-an arm 226 also pivoted on the shaft A spring iliil', Fig. 36, is "connected to the arm [iii and the lug 2 it and holds these two members in contact. This spring prevents the members from swinging idly, but at the same time permits vertical movement of one member relative to the other. Movement of the arm tit caused by the arm engaging the lug Kilt and forcing itto engage the lug iifiii and move the level will shift the am its about its axis till end move the clutch operating arm it?! to the left, Fig. there being a link We operatively connecting the clutch arm til to the lever Clutch mechanism Movement of the clutch arm iii to the left, Fig. 3. causesdisengagement of the clutch 229 and prevents the clutch mechanism 229 from operating the part it of the shaft 8 which concauses the connecting and disconnecting of the parts ii and it of the shaft 3, and therefore controls the operation of the feed and cutter rolls. Inasmuch as the cam which controls the adhesive applicator arm ii is operated by the same mechanism which operates the cutter rolls, this arm will not operate when the feed and cutter rolls do not operate. The coin is operated olirectly 'from the cutter roll shafts and naturally when the cutter rolls do not operate, the cam shafts and cam will not operate. Therefore, the sticker arm ll will not operate. When the clutch operating arm tilt is shifted by the movement of the lever lliitl to the left in Fig. 3, a collar 2232 will first disengage the clutch pawl 23.? from the pawl receiving notch 2%, Fig. 42, in the collar 2%, and then shift the clutch portion 231] out of engage ment with the clutch collar 2%. The clutch pawl or pin is spring-pressed into its receiving notch filial by a spring (Fig. 40). This pawl. is disengaged from its notch or keeper 2%. Therefore, when the lever 227i is shifted to the left, the clutch collars and Zfii are disengaged and the pawl or pin is also disengaged. The part ii of the shaft 3 will, therefore, become disengaged irom part it? of the shaft t. Therefore, upon disengagement, the continuously operating part i? of the shaft 3 can no longer rotate the part it of the shaft ii and inasmuch as the feeding and cutting mechanism is driven from the part iii oi the shaft ii, the feeding and cutting mechanism will become inactive when the clutch is disengaged. The clutch will he maintained in its out-of-ongagement position until it is again positively connected which connection will not occur until a package is in proper position under the detector element tilt. To maintain the clutch out of engagement and in operative position; there is provided an arm pivotelly connected to the clutch operating arrn til at til, Fig. 3.

This arm .iltti has a rigid extension tilt having a receiving recess i239 whichis edept'ed'to receive a pin When the movement of the clutch operating arm tt'i is allthe way to the left to. cause disengagement of the clutch, the pin mill 'is engaged by thelocking enci'ttt as shown in Fig. 33. The locking engagement of the .pinlilfi with the extension 289 occurs due to the fact that the arm tilt is freely pivoted at lllil and therefore when the clutch operating lever 22? swings to the left, the lower arm tilt will swing to the right causing the part tilt to move to the left and upwardly until the locking end 239 is engaged by the pin as clearly shown in Fig. 33. During the next cycle of operation, should there still be no package under the detector element the parts will remain in said locked position with the clutch. out oi engagement. However,

should there be a package under the detector arm 209 during the next cycle of operation, lug Elli, Fig. 33, will be in its lowermost position and en gage the end t ll of the arm When the arm 22i moves toward the left, the movement of the lever 23% to the left will then free the locking end 239 from the pin and cause disengagement of these parts and permit the clutch arm 22! to be moved to the right, disengaging the clutch collar 232 from the part Mill and again permitting the clutch to become engaged at which time the parts ll and iii of the shaft it will again become united to again operate the feeding and cutting mechanism. In cases where the detector arm comes into contact with a package during each cycle of operation, the lug liiil will be in its lowermost position and not in'engagement with the lug 225 and away from the lever 236 so that the clutch operating lever 22? will not be moved by the movement of the rock, arm 22i. The

clutch will therefore remain in engagement, the

parts 9 and it oi the shaft it will be connected and the feeding and cutting mechanism will operate in its regular normal-operative manner. The clutch 229 is normally urged a predetermined distance toward the right, Fig. 3?, by the springs 242 surrounding the pins 2%, the clutch operating collar 232 moving the collar 215i away from the companion collar 23d against the tension 01 the springs M2. The clutch operating arm 22' is normally urged in a predetermined position by a spring 22?, Figs. 3 and 35, there being a stop plate 221" to limit the movement of the arm by the spring. An end ball-bearing thrust bearing 244, Fig. 39, is provided to insure free and easy rotative movement of the parts during engagement of the clutch When the clutch first becomes disengaged, there is a tendency of the clutch collar till over-riding, that is, continuing to rotate and consequently this tendency is transmitted to the ieeding and cutting mechanism. Therefore, to prevent this over-riding action oi the clutch due to kinetic energy, a piece of friction material is fastened to the clutch collar 21 and engages the collar Therefore, when the clutch is thrown out of engagement and the collar 23! is moved away from the collar the friction material on the collar 232 will stop the rotation of the part ill of the shaft immediately.

Preferred detector mechanism A more simple detector mechanism, and the one which is preferably used, is shown in Figs. 47 to 49 inclusive. In this latter embodiment the belt of the conveyor mechanism Si is widened as indicated at Fig. 48 and the detector element 209 acts only as a package detector and not as a timer. In this latter embodiment the detector 2B9 is not controlled by the operation or the pusher 53 and no cam element 263 or pawl 2H8 is required. The detector element 268 is always in its lowermost position and an auxiliary plunger Sill is provided to push a package 5E9 under the detector in the manner shown in Fig. 48. Thus, when there is no package in position against the stop Still, the detector element 263?: will be in its lowermost position as shown in Fig. 49 and cause operation of the clutch 22%. If, however, there is a package under the detector, the mechanism will function continuously, as required. The auxiliary plunger Sill pushes the package from the end of its travel against the stop 302 in a forward direction, against the stop 303 where it will clear the stop and then be carried further against the stop 52 where it is in proper position to be engaged by the pusher upon its next forward movement as shown in Fig. 4'7. The pusher 53 pushes the package 50 in proper position relative to the second pusher 61 where the subsequent cycle of operations is completed as previously described.

Rotary folders Instead of employing the tuckers and folders Hi8 and 558, as previously described, it may be advantageous to use rotary tuckers and folders as shown in Figs. 43 to 46 inclusive wherein con' tinuously rotating fingers 4260 are provided on each side of the package. Thus, when the package is moved from the transfer wheel H by the arms itl, the rotary fingers 306 will rotate in the direction shown by the directional arrow in Fig. 43 and tuck or fold the wrapper along one side of the package at the ends. This-tucking or folding operation occurs because the fingers lilil are operating at a speed greater than the movement of the package 59. These fingers are in timed relationship with respect to the progressive movement of the packages so that a package will be engaged during each complete revolution of a finger. The finger lilil has a blunt rounded end dill which engages the overhanging wrapper at one side of the package and pushes it inwardly against the ends of the package. The rotary folder moves with and faster than the package, but has a relatively long engaging surface illi. These fingers are recessed at 303, Fig. 45, so as to receive the ends of the stationary folders 5%. Thus, as the package is being ad-- vanced in the direction shown by the arrow in Fig. 44, the right-hand side of the wrapper extending from the end of the package will be engaged by the stationary folder dil and cause the wrapper along that side to be folded inwardly. The rotary folder, however, remains in contact with the fold made by it until that fold is received behind the stationary folder 3%. The

rotatably mounted tuckers or folders illll are mounted on shafts 695 which are rotated synchronously and in timed relationship with other operating parts of the machine.

The invention provides a packaging machine which feeds packages to be wrapped along a predetermined path, feeds wrapping web and tape web from individual rolls and in proper timed relationship and in proper position relative to each other and then simultaneously cuts the two webs positioning them in proper position relative to each other and to the package, seals and wraps the wrapper and its cooperating tape about the package leaving a tab to permit the package to be easily opened. Also, the invention contemplates the use of selector mechanism which prevents operation of the feeding and cutting device if a package does not assume a predetermined position on the machine. Furthermore, the machine permits such packages as are already fed into the machine to be wrapped by wrappers already out even though the web feeding and cutting mechanism has been stopped. The novel folders or tuckers of the various types shown and described cause the wrapper to be positively and neatly folded about the package and properly sealed.

The operation of the complete machine has been described throughout the progress of the specification and during the description of the parts and, therefore, further remarks covering the operation are not made.
